How to Install a Bidet

Installing a bidet requires rough-in plumbing lines for hot and cold water and a drain, just like a vanity sink. Placement of a bidet is traditionally next to a toilet, so determine the location when designing the bathroom floor plan. To install a bidet, first determine the location for the bidet and make sure that the wall and floor are square and plumb to ensure a proper installation. Have a plumber run lines for hot and cold water and a drain to meet the rough-in specifications for the bidet.

Most toilet manufacturers offer bidets in styles and colors that complement their toilets. The most typical bidet features a single or two-handle faucet and vertical and horizontal sprays. Although many bidets are open, others incorporate a cover in their design.

Carefully read the installation instructions packaged with the bidet and identify the parts. To install a bidet, you need the following:

Adjustable wrench

Bidet and its mounting nuts and bolts

Carpenter's level

Hot and cold riser tubes

Screwdriver

Silicone sealant

Follow these steps to install a bidet:

Attach the faucet and drain fittings to the body of the bidet.

Move the bidet to its location and check the alignment with the drain and water supply pipes.

Draw a contour of the bidet on the floor and mark the location of the hold-down bolts on the floor.

Remove the bidet and drill pilot holes for the hold-down bolts.

You may have to use a carbide-tipped drill to bore through floor tile.

Connect the water supply and drain and turn on the water to check for leaks.

If the bidet water supply doesn’t have a shut-off valve, add one with hot and cold flexible tubes with preattached fittings that connect the coupling nut to the bidet fitting and the compression fitting to the shut-off valve.
